MOP FRAME AND HANDLE COUPLING.

Specification of Letters Patent.

Original application filed April 17, 1916, Serial No. 91,769. Dividedand this application filed December 21, 1917. Serial No. 208,266.

To all whom it may concern:

Be it known that I, FRANKLIN P. Toor,

a citizen of the United States, and a resident of Paducah, in the countyof Me- Cracken and State of Kentucky,.have invented a new and usefulImprovement in Mop Frame and Handle Couplings, of which the following isa specification. H The present invention relates to mops, and thisapplication is a division of my copending application Serial Number91,769, filed April 17, 1916, for an improvement in mops.

This application is directed more particularly to an improved connectionbetween the handle and the frame of a mop.

The object of the present invention is to provide a coupling orconnection between the handle and the frame of a mop which is simple inconstruction; which removably supports the handle; which pivotallyconnects the handle to the frame in such a manner that the user mayposition or move the mop frame without danger of casual lateraldisplacement of the frame with respect to the handle; and to provide acoupling which may be formed or stamped from a single blank of metal.

Various other objects and advantages of more or less importance will behereinafter described, and in part understood, from the followingdetailed description of the present preferred embodiment, the same beingillustrated in the accompanying drawing, wherein:

Figure 1 is a perspective view of a mop frame and handle connectedtogether by a coupling constructed according to the present invention.

Fig. 2 is a plan view of the same.

Fig. 3 is a side elevation of the same.

Fig. 4 is a detail longitudinal section through the coupling with thehandle applied thereto.

Fig. 5 is a detail perspective view of the coupling partly overturned inthe process of manufacture.

Referring to this drawing A designates a frame which, in the presentinstance may be the frame of a mop, and which may be of triangular formas shown. The frame A has an inwardly offset portion B formed with atransverse section or bearing C to which the coupling of this inventionmay be applied. The frame A is adapted to be is well adapted for use inthe supported by a handle I) having a threaded end portion E preferablyterminating in a shoulder F.

The coupling is formed of a single elongated piece of sheet metal havinga transverse enlargement 10 intermediate its ends,

the enlargement being rounded or bent to form a cylinder of substantiallength adapted to embrace the bearing C and form a support therefor. Theends 11 of the coupling extend from the enlargement 10 and are bentthroughout substantially their lengths into arcuate cross section, asshown to advantage in Fig. 5, and may be provided with screw threads 12formed by pressing the metal inwardly, the ends 11 or sections of thecoupling being complemental to each other and forming a socket forreceiving the screw threaded end E of the handle D.

Each section 11 may be provided with perforated ears 13 in suitablyspaced apart relation from the cylinder 10, and the ears of one sectionabutting against the ears of the other section and adapted to be rivetedfor preventing casual separation of said sections 11 from operativerelation. The threads 12 may extend any suitable distance throughout thelengths of the sections 11, and the latter may be transversel arcuatedthroughout their entire lengths or stiffening or reinforcing thesections of the cou- 'pling.' When the threaded end E of the handle D isturned into the socket between the sections 11, the shoulder F of thehandle is adapted to bear against the free edge of the socket and thusbind the handle in the same.

It is to be observed that the cylindrical portion 10 of the couplingfirmly embraces the cross section 0 of the offset B of the frame, sothat the frame is permitted to swing about a transverse axis, but .isheld firmly against movement about a lateral swinging axis. Because ofthe pivotal connection of the handle with the frame, falling within theplane of the frame, and substantially midway of the front and back ofthe latter, is prevented, and the mop itself cleaning of ceilings,walls, etc., and if it is desired to clean ledges, such as plate rails,the frame A may be swung with respect to handle D so that the latterprojects below the frame for firmly holding the frame during cleaning.

Patented July 27, 1920.

It is of course understood that various changes and modifications may bemade in the details of formation'and design of the above specificallydescribed embodiment of the invention, such changes and modificationsbeing restricted only by the scope of the following claims.

What is claimed is:

1. In a mop, the combination of handle,

a frame, and a coupling formed of a single elongated piece of metaloverturned intermediate its ends and embracing a section of said frame,and the end portions of said coupling being transversely bent to formcomplemental socket portions adapted to embrace the end of said handle.

2. In a mop, the combination of a frame having a transverse bearingsection, a handle for the frame having screw threads on one end, and acoupling comprising a single blank of metal having an enlargementintermediate its ends and overturned to form a cylinder at saidenlargement and having its end portions transversely arcuated to formcomplemental socket sections and having screw threads in the walls ofthe socket sections, and means for securing the socket sections togetherfor the reception of the de tachable threaded handle.

'tion of the metal 3. In a mop, in combination with a handle and a'frame, a coupling formed of a single length of sheet metal benttransversely at opposite ends and overturned With the bent ends togetherto provide complemental socket portions adapted to receive the end ofthe handle, said overturned porbeing rounded and adapted to engage theframe for hinging the coupling thereto.

4. As an article of manufacture, a coupling for mops formed of a singleelongated piece of sheet metal With an enlargement intermediate its endsbent transversely to form a cylinder with its axis crosswise of thecoupling, and the portions extending from said enlargement bent to anarcuate cross section, the last mentioned portions being complementaryto provide a socket With its axis longitudinally of the coupling.

5. A coupling for mop handles comprising a single length of sheet metaloverturned and rounded intermediate its ends to provide a bearingadapted to engage the frame of the mop, the free ends of the sheet ofmetal being curved transversely and brought together to form a socketadapted to receive the end of the handle.

FRANKLIN P. TOOF.
